Fatented Sept. 24, 1907.

Original application filed October 12, 1905, Serial No. 282,395. Divided and this application filed January 19, 1907.

Serial No. 353,054.

To all whom it may concern:

Be it known that I, ALEXANDER MCCARTHY, a citizen of the United States, residing at New York city, New York county, New York, have invented certain new and useful Improvements in Air-Compressors, of which the following is a full, clear, and exact description.

My invention relates to apparatus for generation of power, and particularly for the storage of compressed air.

The object of the invention is to provide apparatus which may be inexpensively constructed and operated and which will serve to compress air economically and without complicated mechanism.

The apparatus herein shown consists of a great many parts, but the principles of the invention are of a simple nature and will be readily understood from the drawings and the following specification.

Briefly the invention may be said to comprise the employment of a series of tubular air compressors adapted when rocked to compress air which is conveyed through suitable pipes or conduits to a storage tank or reservoir conveniently located. This apparatus may be used at the same time as an auxiliary means for rocking a boat to operate an air compressor carried thereby, as described in my application, Serial No. 282,395, filed October 12, 1905, and of which this is a divisional application. The apparatus for rocking the boat I believe to be also novel and useful. This comprises a series of oscillating cylinders partially filled with fluid, together with means for oscillating the cylinders. A series of relatively stationary air compressors is arranged on the interior of the boat and operated by tubular members having longitudinal and oscillatory movements governed by the means for oscillating the cylinders. I have shown the same structure adapted to operation on stationary platforms instead of in a boat. It might be installed for instance on the roof of a building, and adapted to compress air for such uses as may be desired.

Figure 1 is a transverse section showing the mechanism for rocking the boat, together with the relatively stationary air compressors controlled thereby. Fig. 2 is a longitudinal view showing a series of the devices illustrated .in Fig. 1. Fig. 3 is a detail view of one of the oscillating beams and interior air compressor operators. Fig. 4 is a plan View of the carrying beam shown in Fig. 3. Fig. 5 is an end view of the parts shown in Fig. 3. Fig. 6 is a transverse view of a modi iied form of the apparatus shown in Fig. 1, particularly adapted for installation on a stationary support such as a roof or any other place on land.

To supplement the natural operation of the exterior air-compressors, as set forth in my application Serial No. 282,395, filed October 12, 1905, in rough weather,

I have provided means for rocking the boat so as to give additional compression.

1 is a motor or engine of any suitable type, for in stance an electric motor, mounted on the foundation A, which is provided for driving the main shaft 2 through the system of gears 3, 4, 5 and 6. These gears are preferably provided on both sides of the motor so as to give an even drive, but this is non-essential to the principle of the invention, since any method of driving the shaft 2 may be employed.

7 is an oscillating beam arranged transversely of the boat and connected at each end to a crank 8 of the shaft 2 by means of the rod 9.

10 is a cylinder also mounted to swing transversely of the boat and preferably suspended from beneath the deck 11 and connected by a link 12 at each end to the beam '7. When the beam '7 is rocked by the operation of the motor it oscillates cylinder 10, which is partially filled with fluid, preferably water. The principles of the invention would be equally well carried out by the movement within the cylinder 10 of any material which would flow readily from one end to another, such, for instance, as oil, mercury, sand or shot, but for practical reasons I prefer to employ water. As the cylinder 10 is rocked or tilted from its horizontal position the fluid contained therein rushes almost immediately to the depressed end, thus upsetting the stability of the boat, causing it to rock to one side. This brings into operation all the air compressors on the exterior of that side of the boat. When the cylinder is rocked in the other direction the fluid rushes to the other end, rocks the boat and brings into operation all the compressors on that side of the exterior of the boat:

13 is a carrier beam supported by the deck 11 and connected at each end to the cylinder 10 by a link 14.

15 is a tubular member mounted on the carrier beam 13, preferably on wheels on a track so as to move longitudinally thereon when the carrier beam is oscillated with the parts heretofore described. This tubular member is also partially filled with fluid of suitable character, so that when it is rocked or tilted from its horizontal position the fluid will rush to its lower end and cause it to move down to the lower end of the beam 13. This then additionally disturbs the stability of the boat and supplements the operation of the compressors (not shown in this case).

17 represents a compressor of suitable character, for instance a bellows or other suitable compression apparatus, having an outlet tip 18 with a valve device.

19 is a curved yoke secured to the mo'vable part of the compressor.

20 is a rod projecting from the tubular member 15 and having rollers 21 and 22 between which the yoke 19 rests. A compressor is attached to each end of the member 15 and there operated alternately as the memconnect additional beams 13 above.

her 15 moves from one end to the other of the carrier beam 13. The opening of the inlet valve in one compressor permits a substantially free movement of the carrier, so far as it is concerned, while the air is being compressed in the other compressor.

Fig. 2 shows the arrangement of a series of the devices shown in Fig. 1. Here the shaft 23 of the beam 7 carries an auxiliary beam 24 at each end. These are connected by links 12 to the longitudinal rods 25 to which are attached the ends of the oscillating cylinders 10 and the lower ends of the links 14. Otherwise the structure is the same and the operation is the same. An enormous amount of power of slow speed is thus developed by the series of oscillating cylinders 10 and longitudinally movable members 15, together with their relatively stationary air compressors (not shown in Fig. 2).

In the form shown in Fig. 6, particularly adapted for stationary work, the motor 1 is connected by a belt 26 to drive the bevel pinion 27 and screw 28. The latter engages the worm-wheel 29 which is connected by rod 30 to the beam 7. The links 31 at each end of the beam 7 are connected to oscillating beams 13, and links 32 Any number may be employed and they may be arranged longitudinally in series, as shown in Fig. 2. 33 indicates another form of air compressor cylinder having a movable member or piston 34. The parts should be constructed with suitable inlet and outlet valves. 35 is the rod of the piston 34, which is connected to the longitudinally movable and oscillatory tubular member 1.5 which is partly 'filled with fluid, as before described. In this form oi apparatus the tubular members 15 are shown as connected to air compressors only at one end, but the air compressors may be double acting if desired. The compressors being arranged in the form shown will have less tendency to upset the stability of the support than the structure shown in the other figures of the draw ings.

It will be obvious that many changes may be made in the details of construction and in the arrangement of parts without departing from the spirit or scope of my invention.

5. An apparatus for the compression of air, comprising an oscillatory beam, a tubular member mounted thereon and adapted to move longitudinally thereof, and partially filled with fluid, and an air compressing device connected on one end of said tubular member.

6. An apparatus for the compression of air, comprising an oscillatory beam, a tubular member mounted thereon and adapted to move longitudinally thereof, and partially filled with fluid, and an air compressing device connected to each end of said tubular member.
